Glsl shader smoothstep
WebThe first shader I made using these technics was an animated sine wave. The background of the shader is a gradient produced by the sin function, with an x/y plot of the sin function overlaid. The function was plotted using the smoothstep trick show above. To produce the gradient the x position of each pixel is used to produce a black-to-white ...

Webglsl-aastep (glslbin demo) Performs a smoothstep using standard derivatives for anti-aliased edges at any level of magnification. If GL_OES_standard_derivatives is not available, this falls back to using step() without any anti-aliasing. For this module to work, you must enable standard derivatives at your top-level shader:
WebFeb 5, 2014 · Here is a simple morph target animation technique that stores the vertex positions of the morph targets in the original mesh using vertex attribute arrays (glVertexAttribPointer in OpenGL). All morph targets must have the same number of vertices. All animation work is achieved in the vertex shader. Here is the GLSL vertex … WebAug 25, 2016 · Shader A is 2 times slower than shader B.
